ApsaraDB RDS:Set the maintenance window of an ApsaraDB RDS for SQL Server instance

Precautions

• Before the maintenance starts, ApsaraDB RDS sends emails to the contacts that are associated with your Alibaba Cloud account. We recommend that you check your email box on a regular basis to obtain up-to-date information.
• When the maintenance window arrives, your RDS instance enters the Maintaining Instance state. This ensures a smooth maintenance process. Database access and query operations such as performance monitoring are not affected while the instance is in this state. However, except for account and database management and IP address whitelist configuration, modification operations such as upgrade, downgrade, and restart are temporarily unavailable.
• During the maintenance window, one or two transient connections may occur. Make sure that your application is configured to automatically reconnect to your RDS instance.
